Description
CATO supplies Methyl 5-chloro-4-methoxy-2-methylbenzoate (CAS 109803-48-7), a certified reference material (molecular formula C10H11ClO3, MW 214.65 g/mol) for analytical method development and quality control.
The molecular framework of Methyl 5-chloro-4-methoxy-2-methylbenzoate (C10H11ClO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Methyl 5-chloro-4-methoxy-2-methylbenzoate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
